In recent years, research on the noncontact conveyance system with the application of electromagnetic levitation technology has been active. However, because of the strong nonlineality of the attractive force of the electromagnet and the various uncertainties in the circuit current such as changes in the resistance due to heat generation of the electromagnet, the stability of levitation is not sufficiently ensured. In addition, for an actual steel plate conveyance process it will be necessary to develop a control system that takes into consideration various parameter errors, such as nonuniformity of the plate thickness and the associated weight variation. In this paper, we examine the coil resistance variations by heat generation of robustness in the control system using μ-synthesis.
